wkhtmltopdf missing SVG paths (Rendering)

问题

I'm using a image inside the HMTL code like here below:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Test</title>
  </head>
  <body>
    <svg height="291pt" version="1.1" viewBox="0 0 291 291" width="291pt" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> <defs>  <style type="text/css">*{stroke-linecap:butt;stroke-linejoin:round;}  </style> </defs> <g id="figure_1">  <g id="patch_1">   <path d="M 0 291.4 L 291.4 291.4 L 291.4 0 L 0 0 z" style="fill:none;"></path>  </g>  <g id="axes_1">   <g id="line2d_1">    <path clip-path="url(#p6e64365aaf)" d="M 268.427273 145.7 L 207.063636 251.984936 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_2">    <path clip-path="url(#p6e64365aaf)" d="M 248.397453 148.307103 L 199.306544 233.335052 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_3">    <path clip-path="url(#p6e64365aaf)" d="M 207.063636 251.984936 L 84.336364 251.984936 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_4">    <path clip-path="url(#p6e64365aaf)" d="M 84.336364 251.984936 L 22.972727 145.7 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_5">    <path clip-path="url(#p6e64365aaf)" d="M 92.093456 233.335052 L 43.002547 148.307103 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_6">    <path clip-path="url(#p6e64365aaf)" d="M 22.972727 145.7 L 84.336364 39.415064 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_7">    <path clip-path="url(#p6e64365aaf)" d="M 84.336364 39.415064 L 207.063636 39.415064 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_8">    <path clip-path="url(#p6e64365aaf)" d="M 96.609091 55.457845 L 194.790909 55.457845 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>   <g id="line2d_9">    <path clip-path="url(#p6e64365aaf)" d="M 207.063636 39.415064 L 268.427273 145.7 " style="fill:none;stroke:#000000;stroke-linecap:square;stroke-width:1.2;"></path>   </g>  </g> </g> <defs>  <clipPath id="p6e64365aaf">   <rect height="270" width="270" x="10.7" y="10.7"></rect>  </clipPath> </defs></svg>

When I'm using the wkhtmltopdf to convert it to PDF, some of the SVG paths is missing. Has anyone had the same problem? Some workaround to this issue?

I tried using the relative path, full path, base64 source and the SVG by itself within the code (as in the example).

wkhtmltopdf version: 0.12.4

回答1:

So not a exact solution but a far better alternative now is to use a chrome in headless mode

$ chrome --headless --disable-gpu --print-to-pdf test.html
[0427/011400.636954:WARNING:dns_config_service_posix.cc(174)] dns_config has unhandled options!
[0427/011400.638406:ERROR:gpu_process_transport_factory.cc(1007)] Lost UI shared context.
[0427/011400.801881:INFO:headless_shell.cc(586)] Written to file output.pdf.

Also if you want better control on the process, you would use NodeJS and puppeteer

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle2'});
  await page.pdf({path: 'hn.pdf', format: 'A4'});

  await browser.close();
})();
